摘要:
针对大范围内地铁直流牵引回流系统泄漏电流(即杂散电流)难以计算与检测的现状,提出了一种杂散电流泄漏量计算方法,为杂散电流腐蚀危险性的评价提供了基础数据支撑。阐述了基于现有工程技术的杂散电流泄漏量检测方法,并利用MATLAB软件,对计算方法进行了仿真分析。
Abstracts:
Aiming at the present situation of large-scale stray current leakage in DC traction reflux system that is difficult to calculate and measure, a method of calculating the stray current leakage is presented, which provides a basic data support for the evaluation of stray current corrosion risk. Then, with a description of the stray current leakage measurement based on the existing engineering technologies, the calculation method is simulated and analyzed by using MATLAB software.
